The RADCOM QPro is a voice quality performance measurement tool that allows users to objectively measure (PAMS or PESQ), analyse and predict end-to-end speech quality over any network using a traditional PSTN interface.  The QPro offers quality and stress testing of a combination of end-to-end circuit-switched elements, emulating a variety of end-points including PSTN, ISDN, E1, SS7 and Cellular.

Capabilities

• End-to-End voice quality using PESQ or PAMS
• Voice Activity Detection (VAD) Measurements - FEC and HOT
• Delay Measurements - One Way, Round Trip, Utterance
• PSTN, ISDN, E1 and SS7 interfaces
• Supports up to 250 calls per Performer
• Ability to Send & Receive fax transmissions

Tests Performed

The RADCOM QPro provides the user with the capability to emulate a variety of end-points and perform a number of measurements, either pre-defined or on an as-hoc basis, to check the performance of the network to be tested.  Measurements taken including voice quality (PAMS/PESQ), one way delay, round trip delay, echo and others, as well as drill-down capabilities allowing the engineer to investigate issues such as voice activity detection (VAD), Signal Degradation and others.

Summary

A component of the cutting edge Voice over IP (VoIP) Performer, the QPro is designed to help the engineer understand the effect of his network which could be VoIP, Wireless, Satellite or PSTN, on voice quality and assist him in optimising that network to enhance his customer perception of network quality
